Chemical Structure

(d(CH2)51,D-Ile2,Ile4,Arg8)-Vasopressin CAS 88686-53-7 chemical structure

Description

(d(CH2)51,D-Ile2,Ile4,Arg8)-Vasopressin (C49H78N14O10S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(d(CH2)51,D-Ile2,Ile4,Arg8)-Vasopressin (CAS 88686-53-7), molecular formula C49H78N14O10S2 and molecular weight 1087.40 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
